|
36 * SYSEXITS.H -- Exit status codes for system programs. |
|
37 * |
|
38 * This include file attempts to categorize possible error |
|
39 * exit statuses for system programs, notably delivermail |
|
40 * and the Berkeley network. |
|
41 * |
|
42 * Error numbers begin at EX__BASE to reduce the possibility of |
|
43 * clashing with other exit statuses that random programs may |
|
44 * already return. The meaning of the codes is approximately |
|
45 * as follows: |
|
46 * |
|
47 * EX_USAGE -- The command was used incorrectly, e.g., with |
|
48 * the wrong number of arguments, a bad flag, a bad |
|
49 * syntax in a parameter, or whatever. |
|
50 * EX_DATAERR -- The input data was incorrect in some way. |
|
51 * This should only be used for user's data & not |
|
52 * system files. |
|
53 * EX_NOINPUT -- An input file (not a system file) did not |
|
54 * exist or was not readable. This could also include |
|
55 * errors like "No message" to a mailer (if it cared |
|
56 * to catch it). |
|
57 * EX_NOUSER -- The user specified did not exist. This might |
|
58 * be used for mail addresses or remote logins. |
|
59 * EX_NOHOST -- The host specified did not exist. This is used |
|
60 * in mail addresses or network requests. |
|
61 * EX_UNAVAILABLE -- A service is unavailable. This can occur |
|
62 * if a support program or file does not exist. This |
|
63 * can also be used as a catchall message when something |
|
64 * you wanted to do doesn't work, but you don't know |
|
65 * why. |
|
66 * EX_SOFTWARE -- An internal software error has been detected. |
|
67 * This should be limited to non-operating system related |
|
68 * errors as possible. |
|
69 * EX_OSERR -- An operating system error has been detected. |
|
70 * This is intended to be used for such things as "cannot |
|
71 * fork", "cannot create pipe", or the like. It includes |
|
72 * things like getuid returning a user that does not |
|
73 * exist in the passwd file. |
|
74 * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, |
|
75 * etc.) does not exist, cannot be opened, or has some |
|
76 * sort of error (e.g., syntax error). |
|
77 * EX_CANTCREAT -- A (user specified) output file cannot be |
|
78 * created. |
|
79 * EX_IOERR -- An error occurred while doing I/O on some file. |
|
80 * EX_TEMPFAIL -- temporary failure, indicating something that |
|
81 * is not really an error. In sendmail, this means |
|
82 * that a mailer (e.g.) could not create a connection, |
|
83 * and the request should be reattempted later. |
|
84 * EX_PROTOCOL -- the remote system returned something that |
|
85 * was "not possible" during a protocol exchange. |
|
86 * EX_NOPERM -- You did not have sufficient permission to |
|
87 * perform the operation. This is not intended for |
|
88 * file system problems, which should use NOINPUT or |
|
89 * CANTCREAT, but rather for higher level permissions. |
